SPRING-HINGE.

SPECIFICATION forming part of Letters Patent No. 252,164, dated January 10, 1882. Application filed August 18, 1881. (ModeL) To all whom it may concern:

Be it known that I \VILLIAM HILTON WIL- LIAMS,0fBrOOklI1, in the countyofKings and and I do hereby declarethat the following specification, taken in connection with the drawings furnished and forming a part of the same, is a clear, true, and complete description of my invention.

My said improvements relate to that general class of hinges known as spring-butts, and to that well-known special class which embodies'a non-rotative but detachable sleeve for inclosing the spring. The value of the feature of detachability of the sleeve is widely conceded, and the feature of non-rotability enables economy in construction, because sheet metal can then be employed in forming the sleeve and an inexpensive openjoin t left there- 11], which is concealed because 'of its fixed location at the rear, adjacent to a coincident'suu, face of the hinge. If the sleeve be capable of rotation, it must be made of cast metal and seamless; or, if of sheet metal, made with an expensive brazed or soldered joint, because of the desirable finish demanded by the trade.

Heretofore spring-inclosing sleeves have been rendered non-rotative by means of a flange thereon permanently secured to one leaf of the hinge by means ot'pins. For attaining detacha-bility coupled with non-rotability of the sleeve, my invention, broadly stated, mainly consistsin a detachable spring-inclosin g sleeve coupled to a spring-engaging lug located at or within said sleeve, at oneend thereof, and provided with a pin or stud which projects through or occupies a recess or hole in the wall of said sleeve, and arrangedso as to not only co-operate with suitable tension devices as heretofore, but also to lock the sleeve against rotation. This feature of construction is of value regardless of the particular character ot'the tensiondevice employed therewith; but I prefer to employ the same substantially as shown in the drawings and hereinafter described,'and in the specific combinations of parts st-t forth in the several claims hereunto annexed.

It is to be understood that my improvements in no manner relate to that class of spring provemen'ts.

hinges adapted to swing in either direction, and which embody a tubular hinge rod or pintle which contains the spring, and is not detachable, because it is the medium by which the leaves of the hinge are connected.

Referring to the drawings, Figure 1 is a view of an opened butt-hinge" embodying my im- Fig.2 is a perspective View of the spring, its lower lugand its sleeve detached from the hinge and slightly separated longitudinally.

The leaves of the hinge, the tension device a, partially within the sleeve and provided with means for engaging with the upper end of the spring, and the axial rod or hinge pintle for uniting all the parts of the hinge are substantially as heretofore.

It is immaterial what means are employed for uniting the leaves of the hinge so long as said leaves are pivotally connected and axial bearings are afforded for the piutle-socket tension device and for the spring-lug hereinafter described.

The sleeve b differs from prior sleevesin having at its lower end an aperture, as at 0, and the lower spring-lug, d, difiers from prior lugs in being fitted to cylindrically occupy the interior of the sleeve, so that the latter rests wholly on the ear of the hinge, and also in having its projecting pin or stud 6 arranged to pass outwardly through an aperture in the sleeve. The aperture 0, as shown, is in the form of an open recess; but it may as well be a circular or a square-hole, for its sole purpose is to afford the projection of a pin or stud from the lower spring-lug which shall at least lock the sleeve to said lug, and also preferably so as to have the usual bearing of said pin or stud upon the adjacent leaf of the hinge.

Itis obvious that the gist of my invention consists in looking the lower spring-lug to the coincident end of the spring-sleeve, and although the complete housing of thelug within the sleeve is deemed preferable by me, I do not limit myself thereto under the main feature of my invention, because the prime end sought by me will be attained if the lower spring lug be not wholly concealed by the sleeve, but be provided with a vertical or a horizontal pin or stud which will occupy the recess 0, or, the equivalent thereof, a radial hole in the sleeve.

The lower spring-lug, as shown, has its stud or pin cast or formed integrally therewith 3 but it may as well be provided with a single radial hole in its periphery and a pin secured in said hole. While I prefer that the tension device abe a pintle-socket and located, as shown, between the upper end of the sleeve and the lowest of the upper pair of cars, it is obvious that it may be otherwise located and arranged without in any manner departing from the main feature of my invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent' 1. In a spring-hinge, the combination, with a hinge-pintle or its equivalent and suitable tension devices, of a detachable spring-sleeve and a lower spring-lug, which bears on one leaf of the hinge, and to which the'slee've is locked against independent rotation,substantially as described.

2. In a spring-hinge, the combination of a hinge-pintle or its equivalent, suitable tension devices, a detachable sleeve for inclosin g the spring, provided with a hole or recess near one end, and a spring-lug housed within the sleeve, and provided with a pin or stud, which projects through said sleeve and engages with the adjacent leaf of the hinge, substantially rs described.

3. In a spring-hinge, the combination of a hinge-pintle orits equivalent, a spring-inclosing. sleeve, a pintle-socket tension device located between one end of the sleeve and an 5 ear of the hinge, and a spring-lug at the opposite end of the spring, which is locked to said sleeve for preventing independent rotation thereof and bears upon one leaf of the hinge.

4. In a spring-hinge, the combination of a 40 hinge-pintle or its equivalent, a spring-inolosing sleeve, a pintle-socket tension device located between one end of the sleeve and an ear of the hinge, and a spring-lug bearing on one leafofthe hinge, housed within andlocked 5 to said sleeve, and provided with a pin or stud projecting through the sleeve, substantially as described.

5. Man adjustable spring-hinge, the combination ofa hinge-pintle or its equivalent, a spiral spring, a pintle-socket tension device locatedbetiveen one end of the spring and an ear of the hinge, and a spring-lug at the-opposite end of the spring, bearing upon an ear ot'the hinge and provided with a fixed pin or stud for engaging with one of theleaves of the hinge, substantially as described.
